Heartland operates in Langhorne Creek, the maritime-influenced subregion of South Australia's Fleurieu Peninsula. The winery's portfolio centers on Shiraz, the region's signature variety, which thrives in Langhorne Creek's cool-climate conditions and gravelly soils. The Director's Cut Shiraz and flagship Shiraz showcase the varietal's dark fruit and structural depth. Sposa e Sposa, a blend of Lagrein and Dolcetto, reflects an Italian-inflected approach to winemaking. The wines have been assessed by Wine Enthusiast, Wine Spectator, Wine Advocate, Falstaff, and Decanter.
